  • Taper pipe-shaped area flow meter using magnetostrictive distance measurement
    Patent number: 10605634
    Abstract: A taper pipe-shaped area flow meter uses a magnetostrictive distance measurement method through which a flow rate may be accurately measured by measuring a height of a float through a magnetostrictive method. A taper pipe-shaped area flow meter using a magnetostrictive distance measurement method includes a taper pipe including an inlet at a lower portion thereof and an outlet at an upper portion thereof and formed in a taper shape having a diameter decreasing downward, a float in which a magnet is embedded and a height of the float is changed according to a flow rate in the taper pipe, a probe shaft in which a magnetrostrictive line is embedded and which is installed in the taper pipe and detects a position of the float through the magnetostrictive method, and a magnetostrictive distance measuring part, which is configured to apply a pulse to the probe shaft, receive a signal reflected by the magnet of the float, measure a position of the float, and calculate a flow rate from the position of the float.
